The Brazilian mocked City's ambitions of becoming a bigger club than their Old Trafford neighbours as well as castigating the Manchester weather.
He told the People: "When I arrived, the directors at City told me that, in a couple of years, we would overtake United, but the time has passed and nothing has changed.
"Manchester is a sensational venue for football but an awful place to live...the winter, the cold and the dark nights. It's very hard for a young Brazilian.
"The Premier League is one of the best in the world, without a doubt.
"The stadiums are always full and the atmosphere is incredible.
"But not every footballer is able to play in England. The character can be difficult for a foreigner."
